  "textContent": "\n\n\n_Bookmark this page for the authoritative, always-updated overview of NATO’s 2026 training calendar—drill dates, domains, and deployments across the alliance._\n\n\n\n\n**TL;DR:** NATO's 2026 exercise calendar is centred on a Nordic-Baltic axis. **Cold Response 26** (32,500 personnel, completed) anchored the Arctic season. The US Army's new **Sword 26** umbrella — which replaces the **DEFENDER-Europe** brand and restructures its logic — dominates the spring–summer horizon, running late April through May across eight European countries from the High North to Poland. **Sword 26** is linked to Sweden's **AURORA 26** LIVEX and the annual **BALTOPS 26**. Three open-ended **'Sentry'** operations (**Baltic, Eastern, and Arctic Sentry**) provide persistent, year-round posture reinforcement across NATO's flanks.\n\n\n\n\n### Why This Article Matters (and Why You Should Bookmark It)\n\nNATO's exercise calendar is never published in one go. SHAPE populates its schedule incrementally — typically confirming winter/spring drills first, with summer and autumn exercises announced as late as April or May. For journalists, policy analysts, and security professionals, this creates an information gap.\n\nThis guide closes it: a single, evergreen reference updated within 24 hours of any official confirmation. No more piecing together press releases from SHAPE, DVIDS, and a dozen national defence ministries.\n\n\n\n\n* * *\n\n## Interactive Map: NATO Exercises in 2026\n\n_Zoom, click, or hover to explore the geographic distribution of this year’s drills._\n\nStatus All Completed In Progress Upcoming Dates TBC\n\nDomain All Air Land Naval Multi-domain\n\nMarker positions approximate.

Cyber Coalition 26 (referenced in NATO ACT coverage of Cyber Coalition 25; November–December cadence expected).\n\n**Probable but not yet confirmed (annual recurring):** NAMEJS (Latvia, September–October expected; civil-military precursor NATRIX 2026 conducted 24–27 March as scheduled), THUNDER STORM (Lithuania, historically a spring exercise; in recent years folded into the broader Thunder series — Thunder Fortress / Thunder Strike cluster — so a distinct 2026 iteration is uncertain), JOINT WARRIOR 26-1 (UK; no UK MoD or Royal Navy confirmation of execution to date; may be absorbed into Operation Firecrest‑related tasking), DYNAMIC MESSENGER (Portugal/Atlantic, September expected), SANDY COAST, STEADFAST NOON (October expected; host nation not yet announced).\n\n**Confirmed off-cycle or not running in 2026:** HEDGEHOG / SIIL (Estonia runs Spring Storm in 2026; Hedgehog is held in select years only — 2015, 2018, 2022, 2025). ARCTIC CHALLENGE (biennial; ACE 25 was cancelled in June 2025 after US and Danish withdrawals; next iteration 2027). NORTHERN COASTS (paused by Bundeswehr naval command per Marineforum, 28 January 2026; replaced in the Quadriga cluster by Northern QUADRIGA 26). FORMIDABLE SHIELD (biennial, ran 2025, next 2027). SABER GUARDIAN (absent from the Sword 26 lineup after the DEFENDER rebrand; Sword 26 retains Baltic-focused Saber Strike but has dropped the Black Sea–oriented SABER GUARDIAN; no 2026 iteration announced).\n\n\n\n\n* * *\n\n\n\n\n## **Flagship Drills to Watch in 2026**\n\n\n\n\n\n### **Completed**\n\n\n\n\n**ARCTIC DOLPHIN 26 (2–24 Feb, Norway)** An annual ASW exercise off western Norway (Bjørnafjorden, Sognesjøen, Sognefjorden) bringing together Norwegian and allied navies, including Standing NATO Maritime Group One (SNMG1). The drill focused on anti-submarine warfare and certifying new submarine commanders in Arctic maritime conditions.\n\n\n\n\n**DYNAMIC FRONT 26 (26 Jan – 13 Feb 2026, Romania – completed)**.A multinational field artillery command-post and live-fire exercise at Romania's Cincu training centre, practising the Eastern Flank Deterrence Line (EFDL) concept. Eight NATO nations coordinated lethal and non-lethal fires across a distributed battlefield, testing multi-domain kill webs and counter-A2/AD capabilities. The exercise culminated with media day and live fires on 9 February in Cincu. (Overall, up to 23 NATO allies participated across five countries and nine training areas.)\n\n\n\n\n**DYNAMIC MANTA 26 (23 Feb – 6 Mar, Mediterranean Sea)** Major ASW/submarine warfare drill involving submarines, maritime patrol aircraft, helicopters, and surface ships from 10 allied nations: Canada, France, Germany, Greece, Italy, Portugal, Spain, Türkiye, the UK, and the US. Notable first: the exercise integrated an uncrewed surface vehicle (USV) into operations — the first time NATO has incorporated this technology into Dynamic Manta.\n\n\n\n\n**DYNAMIC MARINER 26 (5–20 Mar, Mediterranean Sea)** ARF Maritime Component certification (LIVEX). This year's iteration was geared specifically towards certifying the Royal Navy to assume command of the Allied Reaction Force (Maritime) on 1 July 2026, when the UK takes over the ARF/M lead from the current holder. The exercise drew heavily on Standing NATO Maritime Group 2 (SNMG2), currently under Spanish Navy command, with significant Spanish participation alongside Royal Navy, Italian, Greek and other allied surface, subsurface and air assets. MARCOM used the drill to validate command integration, sustainment, and multi-domain maritime operations in the Mediterranean.\n\n\n\n\n**STEADFAST DART 26 (2 Jan – 18 Mar, Germany / Baltic Sea)**\nNATO’s largest completed exercise of early 2026. The second deployment of the Allied Reaction Force (ARF), and its first under JFC Brunssum. Approximately 10,000–11,000 personnel from 13 nations — including ARF units from Bulgaria, Czechia, Germany, Greece, Italy, Lithuania, Spain, and Türkiye plus linking forces — exercised multi-domain operations at Bergen training area in Lower Saxony with amphibious elements on the Baltic coast.\n\nSome 3,000 vehicles, including 1,000 British, arrived via Emden, testing 'Military Schengen' rail and road logistics. The exercise also produced a notable first: on 20 February, Turkey deployed a Bayraktar TB-3 fixed-wing UAV from the flight deck of TCG Anadolu — the first fixed-wing UAV operation from an amphibious assault ship in a NATO exercise. The TB-3 was subsequently used for live counter-UAS training against German and Italian Eurofighters and Spanish F-18s, supported by a Spanish A400M tanker.\n\nARF elements subsequently transitioned into the German Bundeswehr's Quadriga 2026 cluster — including Grand Quadriga 26, Northern Quadriga 26, and Medic Quadriga 2026 (the Bundeswehr's largest medical service exercise in decades, with 1,250 participants including 250 civilian agency representatives), while the Turkish Maritime Task Group sailed north to join Cold Response 26 — demonstrating the kind of seamless exercise-to-exercise force flow that underpins NATO's 2026 calendar logic. Read our deep-dive on Steadfast Dart 2026 for details:\n\n\nSteadfast Dart 2026: NATO’s First Major Test of the Allied Reaction ForceA deep-dive into Exercise Steadfast Dart 2026 — the Allied Reaction Force’s first operational-scale deployment under JFC Brunssum, and the clearest test yet of NATO’s post-NRF multi-domain readiness architecture.Großwald | European Defence IntelligenceGroßwald\n\n\n**COLD RESPONSE 26 (9–19 Mar, Norway / Finland / Sweden)** The year's premier Arctic exercise. Norway-led, with 32,500 participants from 14 nations — 25,000 in Norway (11,800 on land, the remainder naval and air) and 7,500 in Finland — trained across land, sea, air, cyber, and space domains in Nordland, Troms, and western Finnmark, plus northern Finland. This is the first Cold Response under NATO's new Multi Corps Land Component Command (MCLCC) in Mikkeli, Finland — and the first to fall under the Arctic Sentry umbrella. A large-scale simulation ran in parallel, involving significantly larger simulated forces to increase realism and complexity for participating headquarters. Maritime operations extended into the North Atlantic; air operations spanned all Nordic countries. Participating nations: Norway, Finland, the United States, the United Kingdom, Germany, the Netherlands, France, Italy, Canada, Spain, Türkiye, Sweden, Denmark, Belgium, and NATO. A critical test of JFC Norfolk's operational control over the Nordic region following its assumption of responsibility for the full Arctic AOR. The exercise was led from a joint Norwegian–US headquarters at Reitan, near Bodø. Norway has designated 2026 as the year of 'Total Defence,' and Cold Response was a central component, testing how civilian infrastructure and public institutions support military operations under crisis conditions.\n\nKey developments during execution: The French carrier strike group (Charles de Gaulle), originally scheduled to participate in Cold Response’s maritime component, was retasked by President Macron to the Eastern Mediterranean around 7 March amid escalating Iran tensions. The United States has also withdrawn one squadron of F-35A Lightning IIs that had been scheduled to operate from Ørland, Norway — officials have not confirmed the reason, though concurrent Middle East commitments are the likely factor. These withdrawals reduce the exercise’s high-end maritime and air power contribution but do not affect the core land and Arctic operations.\n\nOn 16 March the defence ministers of Finland, Sweden and Norway issued a joint statement at the exercise site, highlighting substantial progress on NATO’s Forward Land Forces (FLF) Finland. Sweden is providing the core battlegroup, with the objective of achieving operational readiness before the NATO Summit in Ankara this summer.\n\nCold Response 26: NATO’s Largest Arctic Exercise Since the Cold WarNATO’s largest Arctic exercise since 2022 — 32,500 troops, 14 nations, submarine raids, carrier withdrawals, and Russian signalling. Full order of battle, interactive maps, strategic assessment, and 60+ primary sources. Last updated: 1 April 2026.Großwald | European Defence IntelligenceGroßwald\n\n\n**STEADFAST FOXTROT 26 (16–26 Mar, Ulm, Germany)** Sustainment, medical, and enablement wargame hosted by JSEC at Ulm. The 2026 iteration expanded on previous years by adding dedicated medical and sustainment wargames alongside the core enablement rehearsal, and for the first time fed directly into the iterative development of NATO's Reinforcement and Sustainment Network (RSN). Participants rehearsed challenging elements of a reinforcement-by-forces and sustainment operational plan, testing deployment sequencing across 32 allies under the New Force Model structure. Outcomes will feed into the current RSN operational plan ahead of 2027 live exercises.\n\n\n\n\n**NEPTUNE STRIKE 26-1 (25 Mar – 1 Apr, Western & Central Mediterranean)** The first iteration of NATO's premier enhanced Vigilance Activity in 2026, led by STRIKFORNATO from Oeiras, Portugal. The exercise brought together the Spanish Navy's Juan Carlos I expeditionary strike group, the Italian Navy's Cavour carrier strike group, and — participating from the southeastern Mediterranean — the French Navy's Charles de Gaulle carrier strike group. Approximately 3,000 personnel, 15 ships, and 30 aircraft from 12 nations (Albania, Bulgaria, Croatia, Finland, France, Germany, Greece, Italy, the Netherlands, Romania, Spain, and the United States) conducted air and maritime strike operations across the Mediterranean, with air missions extending into continental Europe (Bulgaria, Poland, Romania) and the Black Sea. NATO ISR Force RQ-4D Global Hawks from Sigonella provided surveillance support. SACEUR Gen. Grynkewich visited STRIKFORNATO headquarters during execution. Notably, the exercise focused on NATO's southern and southeastern flanks rather than the originally anticipated multi-theatre North Atlantic/Baltic scope.\n\n\n\n\n**SEA SHIELD 26 (23 Mar – 3 Apr, Romania / Black Sea — completed)** Romania-led multinational naval exercise bringing together approximately 2,500 personnel from 13 nations, with 48 ships, 64 combat vehicles, 10 aircraft, and 20 unmanned systems. Operations spanned maritime, riverine, aerial, land, and underwater domains across the Black Sea and Danube Delta. Romanian Naval Forces provided the core contribution, with frigates  _Regele Ferdinand_ and  _Mărăști_ and minehunter  _I. Ghiculescu_ ; ground elements came from the 1st and 9th Mechanised Brigades and the Multinational Brigade South-East, with French and Spanish contingents. Part of Romania's extensive 2026 exercise programme.\n\n\n\n\n**Value this depth on NATO exercises?**\nGet the full trichotomy delivered free — **Daily Signal** (Mon–Fri), **Weekly Curated** , and **Systems** deep-dives.

Final figures: more than 5,600 personnel from over 40 nations — substantially below the 10,000+ figure projected in earlier USAREUR-AF planning materials. The 2026 iteration was characterised by heavy industry experimentation: more than 30 US-based industry partners fielded capabilities including AI decision-support systems, robotic targets for live fire, ground sensing, and FPV drone operations against moving armoured targets. A multi-language AI capability delivering real-time Arabic-to-English translation over MPU5 radios was validated at Southern Zone Headquarters in Agadir on 4 May. Italian and French special operations units partnered with Tunisian counterparts on airborne operations and joint targeting. C-130 dirt landing certification — rarely available in Europe — was a standout training opportunity. The culminating live-fire phase took place at Cap Draa near Tan-Tan on 8 May.\n\n\n\n\n**NEPTUNE STRIKE 26-2 (late Apr – 30 Apr, Mediterranean)** Led by STRIKFORNATO from Oeiras and concluded 30 April. The second 2026 iteration of NATO's premier enhanced Vigilance Activity spanned NATO's southern and south-eastern flanks. The French Carrier Strike Group around FS  _Charles de Gaulle_ led the maritime component, with attached Italian, Spanish, and Netherlands frigates. The US carrier strike group originally scheduled to lead alongside the French CSG did not participate; ongoing Middle East commitments resulted in the US foregoing the iteration entirely. Participating forces drew from Albania, Bulgaria, France, Greece, Italy, Montenegro, Portugal, Romania, Türkiye, and the United Kingdom. Air missions included RAF Typhoons and Romanian F-16s under Allied Air Command. The activity was formally framed as part of NATO's networked enhanced Vigilance Activity architecture alongside Eastern Sentry, Arctic Sentry, and Baltic Sentry. The French CSG transited the Suez Canal on 6 May en route to the Red Sea as part of the Anglo-French maritime coalition reinforcing freedom of navigation in the Strait of Hormuz.\n\n\n\n\n**NATO TIGER MEET 2026 (4–15 May, Araxos AB, Greece)** The Hellenic Air Force's 335 Squadron hosted the 2026 iteration of NATO's longest-running multinational air exercise at Araxos Air Base. Nine Allied nations participated — Belgium, Czechia, Germany, Greece, Hungary, Italy, Poland, Spain, and Switzerland — with observers from Austria, France, the United Kingdom, India, and the Netherlands. More than 50 fighter aircraft and helicopters flew daily missions across the Athens Flight Information Region, with approximately 1,000 personnel deployed. Platforms included F-16 Fighting Falcons, Eurofighters, Gripens, Tornados, F/A-18 Hornets, AW101 Merlins, and Venom helicopters. Mission sets covered defensive and offensive counter-air, air interdiction, dynamic targeting, suppression and destruction of enemy air defences (SEAD/DEAD), and air power contribution to counter-land and counter-maritime operations. The Best OPS trophy went to Belgium's 31 Squadron operating F-16A/B MLU; the Silver Tiger to Italy's 12° Gruppo. The Tiger Association traces back to 1961.\n\n\n\n\n**AURORA 26 (27 Apr – 13 May, Sweden)** Swedish-led multinational LIVEX involving 18,000 personnel from 13 nations across Sweden, the Baltic Sea, and Gotland. Sweden's first Aurora exercise as a fully integrated NATO Ally, and a large-scale rehearsal of NATO-adapted operational defence plans under collective defence. Approximately 16,000 Swedish personnel were augmented by 1,500 allied troops from 12 nations, with Ukrainian drone operators participating under the JEF–Ukraine Enhanced Partnership agreed at the Oslo summit in May 2025. Around 1,300 personnel from the United States, the United Kingdom, Denmark, and Ukraine reinforced Gotland — the focal point of Baltic Sea defence — during the concluding combined-arms phase on 11 May. The exercise also previewed elements of the distributed operations and multi-domain integration central to Ramstein Flag 26 in June. Linked to Sword 26 under the same Key Strategic Activity framework within a Germany-led Consolidated Strategic Opportunity.\n\n\n\n\n**STEADFAST DETERRENCE 26 (5–13 May, NATO-wide)** SHAPE's premier deterrence and collective defence exercise at strategic and operational levels, directed by the Joint Warfare Centre at Stavanger. Approximately 8,000 military and civilian staff from all 32 NATO member states participated across SHAPE, all Allied Command Operations joint and domain headquarters, and multiple locations across Europe and the United States. The third iteration of the series, and the first to implement NATO's new Campaign Approach to Exercises — designed for greater realism, increased warfighting readiness, and enhanced multi-domain command and control. The scenario focused on the Arctic and the High North, stress-testing NATO's integrated military plans under the Concept for Deterrence and Defence of the Euro-Atlantic Area. The first JWC exercise to incorporate AI-enabled warfighting platforms into scenario delivery.\n\n\n\n\n**TROJAN FOOTPRINT 2026 (11–22 May, multi-country)** The largest US Special Operations Forces-led exercise ever conducted in Europe, concluded 21 May. US Special Operations Command Europe (SOCEUR) led approximately 3,000 personnel — 1,000 US service members and 2,000 SOF operators from 23 NATO Allies and partner nations. Robust participation came from Bulgaria, Croatia, Estonia, Georgia, Germany, Greece, Hungary, Latvia, Lithuania, North Macedonia, Poland, and Romania. Operations spanned multiple training locations across the European theatre, with notable maritime infiltration activity in the Gulf of Elefsina (Greece) on 13 May. Training covered the full SOF competency spectrum — reconnaissance, sensitive-site operations, direct action — and served as a testbed for hybrid-threat response concepts and new operational technologies. Lt. Gen. Richard Angle, SOCEUR commander and head of NATO Special Operations Command, framed the exercise as a demonstration that the Alliance has \"both the will and the capability to defend every inch of the Alliance.\" Trojan Footprint has been biennial since 2016.\n\n\n\n\n**NATO–SERBIA EXERCISE 2026 (May, Bujanovac, Serbia)** The first-ever joint military exercise between NATO and the Serbian Armed Forces, hosted in Bujanovac and concluded in late May. Approximately 600 troops from NATO allied nations trained alongside Serbian personnel over two weeks in peace support operations. Participants: Serbia, Italy, Romania, Türkiye, France, Germany, Montenegro, the United Kingdom, and the United States. Led on the NATO side by JFC Naples (Admiral George M. Wikoff). Modest in scale but historically significant as a precedent for practical NATO–Serbia military cooperation despite Belgrade's formal non-alignment.\n\n\n\n\n* * *\n\n\n\n\n### **In Progress**\n\n\n\n\n**SWORD 26 (27 Apr – 31 May, High North / Baltic / Poland)** USAREUR-AF's rebranded and restructured successor to the DEFENDER series, in its final week as of this update. Approximately 15,000 troops from 11 nations operate across eight countries from distributed locations in the High North, Baltic region, and Poland, organised around three linked exercises: Saber Strike (Baltic / Poland), Immediate Response (High North), and Swift Response (specialised deployment). Gen. Christopher Donahue, USAREUR-AF commanding general, has framed the exercise around AI-enabled warfighting at scale and the operationalisation of the Eastern Flank Deterrence Initiative (EFDI). Notable activity includes: the 2d Cavalry Regiment's tactical road march from Vilseck, Germany to Poland and Lithuania, departed 27 April; a Saber Strike combined-arms rehearsal at Bemowo Piskie Training Area, Poland on 5 May; Polish exercise Amber Shock 26 at the Orzysz training ground 60 km from the Kaliningrad oblast border, involving 3,500 troops; and the main Saber Strike fires phase at the Vuosanga training area in Finland's Kainuu region, near the Russian border. Sword 26 represents the first practical application of in-theatre force employment under the post-DEFENDER doctrinal shift, validating NATO's regional defence plans rather than rehearsing transatlantic reinforcement. Linked to AURORA 26 under the same Key Strategic Activity framework within a Germany-led Consolidated Strategic Opportunity.\n\n\n\n\n**DYNAMIC MONGOOSE 26 (18–29 May, Norwegian Sea / High North)** NATO's principal annual anti-submarine warfare exercise in the High North, led by NATO Allied Maritime Command and hosted by Norway in its alternating Norway–Iceland cadence (DM25 was hosted from Reykjavík). Surface operations are hubbed at Trondheim, with air assets supported from Stavanger; Rear Admiral Bret Grabbe, Commander Submarines NATO, commands the task force. Nine nations participate — Germany, Norway, Denmark, Portugal, France, the Netherlands, Canada, the United Kingdom, and the United States — with submarines, surface ships, and maritime patrol aircraft operating across the Norwegian Sea and the GIUK-N Gap. Standing NATO Maritime Group 1 (SNMG1) provides the core surface element, and HMS Prince of Wales has integrated into the ASW task force following her Stavanger port call — effectively folding Operation Firecrest's Phase 1 air group into the Dynamic Mongoose AOR. On 21 May, NATO MARCOM reported that the SNMG1 frigate NRP Dom Francisco de Almeida (F334) and a Royal Navy Merlin Mk2 from HMS Prince of Wales shadowed the Russian surveillance ship Yury Ivanov, which had been loitering near exercise forces.\n\n\n\n\n**SPRING STORM 2026 / KEVADTORM 26 (4 May – 1 Jun, Estonia + NE Latvia)** The 20th iteration of Estonia's largest annual exercise, conducted in alternation with Hedgehog (Siil), which last ran in 2025. Over 12,000 troops at peak, with participating contingents from Latvia, Lithuania, the United States, the United Kingdom, Canada, Finland, Sweden, Denmark, the Netherlands, France, Poland, Ukraine, Czechia, Germany, Romania, and Portugal. Primary training audiences are the 2nd Infantry Brigade (Estonian Division) and Regional Command South (Estonian Defence League). The exercise unfolds in three phases: division-level command-post exercise (4–9 May), unit training and force-on-force battles in south-eastern Estonia and north-eastern Latvia (10–22 May), and live-fire at the Central Training Area (23 May – 1 June). Spring Storm 2026 sits adjacent to the Sword 26 footprint and shares national contingents with the broader Nordic-Baltic cluster.\n\n\n\n\n**OPERATION FIRECREST (5 May onwards, North Atlantic / High North — Phase 1)** HMS  _Prince of Wales_ sailed from Glen Mallan, Scotland on 5 May for the first phase of Operation Firecrest, leading a small task group on exercises across Nordic waters and the High North. Composition is significantly reduced from the original February announcement: the carrier is accompanied by Type 45 destroyer HMS  _Duncan_ and RFA  _Tidespring_ , under Commodore Rich Hewitt, Commander UK Carrier Strike Group. The embarked air group is initially helicopter-heavy; fixed-wing assets remain scarce, with at least eight F-35Bs deployed to Cyprus and high demand on the Lightning Force following the nine-month Operation Highmast in 2025. US participation, originally framed as central to the deployment via cross-deck operations and a US port visit, has not yet been confirmed; the original timeline for a full CSG deployment alongside SNMG1 (HMS  _Dragon_ leading) remains under refinement. Phase 1 falls under NATO's Arctic Sentry mission.\n\n\n\n\n**MARE APERTO 26-1 (3–27 May, central Mediterranean)** The Italian Navy's principal annual high-end maritime exercise, conducted in the central Mediterranean with NATO forces and French Navy participation. Initial Planning Conference held 11–12 February at Comando in Capo della Squadra Navale (Santa Rosa, Roma). Scenarios span CBRN response, cyber defence, public information, environmental and heritage protection, humanitarian assistance, and high-end multi-domain operations. The exercise integrates ITA MINEX 26 (Italian Mine Warfare Exercise) and serves as a key test of Italian Navy combat readiness across the spectrum. Concludes 27 May.\n\n\n\n\n**OPEX 26 (18–29 May, Mangalia / Black Sea)** Romanian Naval Forces-led operational experimentation exercise focused on autonomous maritime systems, conducted in the military port of Mangalia and adjacent Black Sea areas. Six NATO nations participate — Bulgaria, Canada, Portugal, Romania, the United States, and Türkiye — alongside civilian unmanned-systems manufacturers. Approximately 1,000 personnel and 50 pieces of equipment are involved. Romanian assets include diver-support vessel  _Grigore Antipas_ , minesweeper  _Capt. Constantin Dumitrescu_ , and hydrographic vessels  _Ocean 1_ and  _Ocean 2_. Exercise focus: surface and underwater unmanned-system employment and tactical manoeuvres to strengthen multinational interoperability. OPEX 26 is the fourth in a sequence of NATO-relevant exercises on Romania's Black Sea coast since March. Not to be confused with EDA's separate OPEX 2026 — a European Defence Agency operational experimentation campaign scheduled for October at Santa Margarida, Portugal.\n\n\n\n\n**KARELIAN SWORD 26 (22–29 May, Southeastern Finland)** The Finnish Army's principal spring exercise, led by the Karelian Brigade under Col. Ari Määttä across the Kymenlaakso, South Savo, and South Karelia regions. Approximately 10,000 personnel — 5,800 conscripts, 2,700 reservists, and 1,400 Finnish Defence Forces personnel — alongside ~1,500 vehicles and significant air activity. Allied participation: the US Virginia National Guard and a UK Army attack-helicopter unit. The exercise sits adjacent to Sword 26's Finnish component and forms part of a broader Finnish Army exercise series involving 19,000 personnel across Finland in May. The training area extends within tens of kilometres of the Russian border with the Leningrad and Karelia regions, and serves as the final exercise for conscript leaders trained in the 2/25 and 1/26 cohorts.\n\n\n\n\n* * *\n\n\n\n\n### **Upcoming**\n\n\n\n\n**BALTOPS 26 (4–19 Jun, Baltic Sea region)** The 55th iteration of NATO's premier annual maritime exercise in the Baltic. Led by US Naval Forces Europe-Africa / Sixth Fleet and command-and-controlled by STRIKFORNATO from Oeiras. Planning was hosted by the Finnish Navy Command in Turku, 14–16 April. Expected scope: amphibious operations, gunnery, air defence, anti-submarine warfare, mine countermeasures, explosive ordnance disposal, medical response, and unmanned surface/underwater vehicle integration. The Finnish Navy describes BALTOPS 26 as conducted under the Arctic Sentry umbrella — an unusual command framing given Baltic Sentry's pre-existing remit, and worth watching for clarification at execution.\n\n\n\n\n**RAMSTEIN FLAG 26 / RAFL26 (8–19 Jun, Norway / Finland / Sweden / Denmark / Spain)** NATO Allied Air Command's premier live-fly exercise. The third iteration of the Flag-series since its 2024 launch, and the first to be led independently by AIRCOM. Approximately 19 nations, more than 150 aircraft, and roughly 150 sorties per day across NATO's Joint Operations Area North-West (Nordic) and Joint Operations Area South-East (Mediterranean) — operations stretch from the northernmost parts of Norway to the southern reaches of Spain. Strategic priorities: Counter Anti-Access/Area Denial (C-A2AD), Integrated Air and Missile Defence (IAMD), Agile Combat Employment (ACE), and improved multi-domain information-sharing. Live-fly missions are combined with synthetic training. RAFL26 builds directly on the air-component lessons from AURORA 26 and represents the largest planned air-domain training event of 2026. The Tactical Leadership Programme at Albacete serves as the main hub for JOA SE; Kallax Air Base in northern Sweden hosts JOA NW media activity on 16 June.\n\n\n\n\n**LION PROTECTOR 26** **(September, Iceland / Danish Straits / Norway)** The signature 2026 exercise of the UK-led Joint Expeditionary Force, confirmed by the UK Ministry of Defence on 11 February 2026 and reinforced by the JEF leaders' joint statement from the Helsinki summit on 26 March. Air, land, and naval forces from JEF nations — Denmark, Estonia, Finland, Iceland, Latvia, Lithuania, the Netherlands, Norway, Sweden, and the UK — will deploy across Iceland, the Danish Straits, and Norway to train on the protection of critical national infrastructure against sabotage and attack, and to exercise joint command and control across the High North, North Atlantic, and Baltic approaches. Ukrainian units will participate under the JEF Enhanced Partnership framework agreed in Oslo last year. The exercise sits alongside the UK's doubling of its permanent troop presence in Norway (from 1,000 to 2,000 personnel over three years) and is framed by London as the JEF's principal contribution to the NATO Arctic Sentry posture. Exact dates within September have not yet been released.\n\n\n\n\n* * *\n\n\n\n\n### **Persistent Operations: The 'Sentry' Triad**\n\n\n\n\nA defining feature of NATO's 2026 posture is the simultaneous operation of three open-ended, multi-domain activities — distinct from calendar exercises and running without a stated end date:\n\n\n\n\n**ARCTIC SENTRY (launched 11 February 2026)** — The newest addition, placing all allied Arctic activity under a single coordinated command for the first time. Led by JFC Norfolk, coordinating with NORAD, USNORTHCOM, and USEUCOM. Denmark's Arctic Endurance, Cold Response 26, and the UK's Operation Firecrest (Phase 1 underway since 5 May) all fall under this umbrella. The Finnish Navy has also framed BALTOPS 26 under this command structure, an unusual framing worth confirming at execution. Born from the Davos Rutte–Trump framework on Greenland and NATO's stated concern over both Russia's increasing military activity and China's growing interest in the Arctic.\n\n\n\n\n**BALTIC SENTRY (launched 14 January 2025)** — Enhancing NATO's maritime presence in the Baltic Sea, prompted by suspected Russian undersea sabotage of energy pipelines and communications cables. Incorporates naval surveillance drones, warships, submarines, and aircraft. In February 2026, eight Baltic-region allies signed a letter of intent to advance Task Force X-Baltic — NATO's autonomous maritime surveillance initiative — from experimental testing to nationally owned, NATO-taskable capabilities, a direct outgrowth of Baltic Sentry's operational requirements.\n\n\n\n\n**EASTERN SENTRY (launched 12 September 2025)** — Bolstering NATO's air, land, and sea posture along the entire eastern flank, from the High North to the Black Sea. Triggered by Russian aircraft and drone incursions into allied airspace. Integrates traditional capabilities with counter-drone sensors and novel technologies. Contributions from Denmark, France, Germany, the UK, and others.\n\n\n\n\n**Key Insight:** Until 2025, NATO demonstrated readiness through exercises — large-scale drills with fixed dates that began, ran, and ended. The three Sentries work differently: they are ongoing operations with no end date, keeping allied forces permanently deployed across the Baltic Sea, the eastern flank, and the Arctic simultaneously. NATO has not maintained this kind of continuous, multi-theatre military presence since the Cold War.\n\n* * *\n\n\n\n\n## **Regional & Domain Hot-Spots**\n\n\n\n\n### **Northern Flank & Arctic Security**\n\n**Cold Response 26**(9–19 March, completed) anchored the Arctic calendar under **Arctic Sentry's umbrella** , though its maritime and air components were reduced by the withdrawal of a US F-35 squadron from Ørland. **Arctic Dolphin 26** (completed February) tested ASW in Norwegian fjords. Denmark's Arctic Endurance ran concurrently in and around Greenland. **Operation Firecrest's Phase 1** — HMS  _Prince of Wales_ with HMS  _Duncan_ and RFA  _Tidespring_ — sailed from Scotland on 5 May. The Nordic **Arctic Challenge** Exercise is biennial and is not running in 2026 (next iteration 2027).**Steadfast Deterrence 26** (5–13 May, completed) followed as the strategic CPX counterpart, focused on the Arctic and the High North under SHAPE's new Campaign Approach to Exercises. **Ramstein Flag 26**(8–19 June) will exercise allied air power from northern Norway. **Lion Protector 26** , the UK-led JEF exercise across Iceland, the Danish Straits, and Norway, is confirmed for September.\n\n\n\n\n### **Baltic & Nordic Deterrence**\n\n**Steadfast Dart 26**(January–March, completed) tested the ARF's rapid deployment into northern Germany. The Nordic-Baltic centre of gravity in May 2026 was formed by four concurrent exercises: **Sword 26** (27 April – 31 May, in final week), Sweden's **AURORA 26**(27 April – 13 May, completed with 18,000 personnel including Ukrainian drone operators on Gotland), Estonia's **Spring Storm 2026** (4 May – 1 June, 12,000+ personnel), and Finland's **Karelian Sword 26** (22–29 May, 10,000 personnel with US and UK contingents). **Trojan Footprint 2026** (11–22 May, completed) provided the SOF layer across multiple Eastern European countries. **BALTOPS 26** (4–19 June) and **Ramstein Flag 26** (8–19 June) carry the cluster into early summer. **Namejs** (Latvia) is expected to recur in September–October but is not yet confirmed for 2026; **Thunder Storm's 2026** status remains uncertain following the Lithuanian Thunder series' restructuring around **Thunder Fortress** and **Thunder Strike**.\n\n\n\n\n### **Black Sea & Southeastern Flank**\n\n**Dynamic Front 26**(February) tested multi-domain fires at Romania's Cincu. **Sea Shield 26** (23 March – 3 April, completed) was the flagship Black Sea naval drill, led by the Romanian Armed Forces with approximately 2,500 personnel from 13 nations and significant French and Spanish contributions. OPEX 26 (18–29 May, in progress) extends the Romanian Black Sea programme into unmanned maritime systems, with six NATO navies operating from Mangalia. Romania's broader 2026 programme also includes **Carpathian Arc 26** (MNC-SE led), **DACIA 26**(linked to Steadfast Defender 27), **Land Shield 26** , **HISTRIA 26** , and **Burebista 26**. NATO–Serbia Exercise 2026, while modest in scale (~600 troops in Bujanovac), marked the first-ever joint exercise between NATO and the Serbian Armed Forces. Eastern Sentry continues to provide persistent air defence and surveillance from the High North to the Black Sea.\n\n\n\n\n### **Mediterranean & North Africa**\n\n**African Lion 26** (20 April – 8 May, completed) closed with a final force of more than 5,600 personnel from over 40 nations across Morocco, Tunisia, Ghana, and Senegal — substantially below pre-execution projections of 10,000+ personnel. The Mediterranean saw **Dynamic Manta 26** (completed March), **Dynamic Mariner 26** (completed March), **Neptune Strike 26-1** (25 March – 1 April, completed) — which brought together the Spanish  _Juan Carlos I_ ESG, Italian  _Cavour_ CSG, and French  _Charles de Gaulle_ CSG across the western and central Mediterranean with contributions from 12 nations — NATO **Tiger Meet 2026** (4–15 May at Araxos AB, completed), **Mare Aperto 26-1** (3–27 May, Italian Navy-led with NATO and French Navy participation, concluding), and **Neptune Strike 26-2** (concluded 30 April). The latter was conducted without US carrier participation; the French CSG around FS  _Charles de Gaulle_ led the activity, transiting the Suez Canal on 6 May en route to the Anglo-French maritime coalition in the Strait of Hormuz. The Mediterranean theatre's strategic centre of gravity has accordingly shifted south and east through the spring.\n\n\n\n\n* * *\n\n\n\n\n* * *\n\n\n\n\n## Frequently Asked Questions\n\n\n\n\n**What is the biggest NATO exercise in 2026 so far?**\n\nCold Response 26 (9–19 March), with 32,500 personnel from 14 nations across Norway and Finland, was the largest NATO live exercise of 2026 so far. AURORA 26 (27 April – 13 May, 18,000 personnel from 13 nations) and Sword 26 (15,000 troops from 11 nations across eight countries) followed in the spring. Steadfast Dart 26 (2 January – 18 March) involved approximately 10,000 troops and 3,000 vehicles from 13 nations.\n\n**What are the 'Sentry' operations?**\n\nBaltic Sentry, Eastern Sentry, and Arctic Sentry are open-ended, multi-domain activities — not time-limited exercises. They provide persistent NATO presence and surveillance across the Baltic Sea, the eastern flank, and the Arctic respectively. Arctic Sentry, the newest, was launched on 11 February 2026.\n\n**Why isn't the full 2026 calendar published yet?**\n\nNATO and SHAPE release exercise details incrementally. Winter and spring drills are typically confirmed first; summer and autumn exercises are announced as late as April or May. This guide is updated within 24 hours of any official confirmation.\n\n**Are these drills offensive in nature?**\n\nNATO classifies all exercises and operations as defensive and deterrent, designed to protect allied territory under Article 5 and improve interoperability.\n\n**Is this guide still being updated?**\n\nYes — continuously.
